We began at 6am and shut her down by 9:30am. The stream temperatures were rising quickly and we decided the trout could not endure such hot water temperatures so we called it a day.

Water temperatures anywhere near 70 degrees can kill trout even if the trout is brought to shore quickly and released properly. There is not enough dissolved oxygen in the water and the trout suffocate after the release.
